HOW systems work

摘要

The technology used to treat ballast water has generally been derived from other industrial applications, in which forms of solid-liquid separation and disinfection processes were applied. The separation process concerns the removal of solid suspended material from the ballast water by sedimentation or straining by means of a filter. This produces a waste stream that comprises backwash water from the filtering or a hydrocyclone operation. The waste stream is discharged during ballasting.
